sculpture
waist weakly sculptured
The lateral portions of petiole and postpetiole are weakly sculptured to lacking sculpture, giving them a shiny appearance. Used in Antkey to separate the minor worker of Pheidole fervens from that of Pheidole obscurithorax.
gaster punctate
The first gastral segment is entirely punctate. Used in Antkey to separate Strumigenys eggersi from Strumigenys gundlachi.
gaster smooth
The first gastral segment is smooth and lacking punctation over its entire surface. Used in Antkey to separate Strumigenys gundlachi from Strumigenys eggersi.
head smooth posteriorly
The posterior third of cephalic dorsum smooth and shining with at most a few short interrupted carinae. Used in Antkey to separate major workers of Pheidole megacephala from those of other Pheidole species.
head sculptured posteriorly
The posterior third of cephalic dorsum distinctly sculptured either with punctures or carinae, but never smooth and shining. Used in Antkey to separate major workers of various Pheidole species from Pheidole megacephala.
posterolateral lobes punctate
The posterolateral lobes with a distinct punctate ground sculpture, giving the head a dull appearance, and also lacking rugae. Used in Antkey to separate the major workers of Pheidole anastasii, Pheidole bilimeki and Pheidole punctatissima from those of all other Pheidole species.
posterolateral lobes rugose
The posterolateral lobes distinctly rugose and the lack of a punctate ground sculpture gives the head a shiny appearance. Used in Antkey to separate the major workers of Pheidole fervens, Pheidole flavens, Pheidole moerens, Pheidole obscurior and Pheidole teneriffana from those of all other Pheidole species.
